Embryo-fetal developmental toxicity of carbamazepine administered orally in wistar rat
Carbamazepine is an anticonvulsant medication commonly used to treat epilepsy and other neurological disorders. The purpose of this study was to assess the impact of carbamazepine on prenatal development, including maternal-fetal, external, visceral, and skeletal toxicity. Additionally, the study aimed to investigate the effects of orally administered Carbamazepine at a lower dose range in Wistar rats. Pregnant female rats were randomly distributed into control (G1) group administered with distilled water orally (n=8), low dose (G2) group administered at 25 mg/kg, intermediate dose (G3) group at 50 mg/kg, and high dose (G4) group at 100 mg/kg through oral gavage from gestation day (GD) 5–19. Pregnant female rats were scheduled to necropsy on gestation day (GD) 20. During the evaluation, the uterus was observed for number of live or viable fetuses, dead fetuses, early resorptions, late resorptions, number of corpora lutea and the sex ratio (m/f) per litter. Further, fetuses were subjected to materno-fetal examination which included observation for placenta, amniotic fluid, and umbilical cord followed by external evaluation. Additionally, half of the fetuses were subjected to visceral, craniofacial evaluation and other half of the fetuses were subjected to skeletal evaluation by double staining method using Alcian Blue for cartilages and Alizarin Red S for bones. It was observed that there was a significant decrease in the rate of pregnancy in the intermediate dose (G3) group and in high dose (G4) group when compared with the control group. Moreover, treatment with the Carbamazepine caused significant increase in fetal malformations such as dilation of lateral and third ventricle in brain, in intermediate dose (G3) group and high dose (G4) group when compared with the control (G1) group, dilation of ureters in high dose (G4) group. Fetal skeletal malformations like bent and nodulated ribs were also observed in intermediate dose (G3) group. Existing research substantially supports the claim that carbamazepine can cause teratogenic effects and prenatal development toxicity even at a lower dose range.
期刊介绍：
Drawing from a large number of disciplines, Reproductive Toxicology publishes timely, original research on the influence of chemical and physical agents on reproduction. Written by and for obstetricians, pediatricians, embryologists, teratologists, geneticists, toxicologists, andrologists, and others interested in detecting potential reproductive hazards, the journal is a forum for communication among researchers and practitioners. Articles focus on the application of in vitro, animal and clinical research to the practice of clinical medicine.
All aspects of reproduction are within the scope of Reproductive Toxicology, including the formation and maturation of male and female gametes, sexual function, the events surrounding the fusion of gametes and the development of the fertilized ovum, nourishment and transport of the conceptus within the genital tract, implantation, embryogenesis, intrauterine growth, placentation and placental function, parturition, lactation and neonatal survival. Adverse reproductive effects in males will be considered as significant as adverse effects occurring in females. To provide a balanced presentation of approaches, equal emphasis will be given to clinical and animal or in vitro work. Typical end points that will be studied by contributors include infertility, sexual dysfunction, spontaneous abortion, malformations, abnormal histogenesis, stillbirth, intrauterine growth retardation, prematurity, behavioral abnormalities, and perinatal mortality.
